Another option is selling the Virtus and buying a WWSD2020 from Brownells. The Virtus is listed at 7.9 lbs, and the WWSD2020 at 4lbs 15oz. Might also have a few dollars left over in your pocket too...
No, the wwsd2020 is not the Brn-180. It is a ‘standard’ DI AR15 built on a KE Arms polymer lower, faxon 16” pencil barrel, and carbon fiber hand guard. It retains all of the adaptability of the standard AR platform, with none of the negatives you cite. It’s chief claim to fame is being light weight and handy. No, it is not a piston gun, and no, it cannot be fired with a folded stock, but it is 2+ POUNDS lighter than the virtus. I do not own one and don’t ‘have a dog in the fight.’ My point is that if you find the Virtus heavy, there’s not much you can do to lighten it appreciably- other than to off load it and buy something lighter.If the WWSD2020 (What Would Stoner Do) is the BRN-180, then it is NOT even close to the Sig Virtus in flexibility or capability.
The BRN-180 has these negatives compared to the Virtus:
- A reciprocating charging handle
- Unable to change barrels at customer level
- Unable to change Handguard at customer level
- Unable to change caliber at customer level
I have both and would NEVER consider a BRN-180 equal to or even close to a Virtus. If the OP wanted a light weight setup, the Virtus isn't it. But they are insanely popular right now, so he can sell it and get some pencil barreled ultra light weight configuration, that lacks the capabilities, features, and flexibility of the Sig Sauer Virtus.
